Re: How to retrieve access token from refresh token?

[Aurelien D]

Here is the PHP  code i use once i have the refreshToken and the user has authorized his data to be used.

It will normally give you a new access_token with a new expiring time. It will echo it on the screen and also connect to the calendar api (you have to activate it it the google api console) to return the possible colors of calendar and the list of the calendars.

Hope to answer well to your question.

Why not use 

$refreshToken = retrieve from database...

$new_token = client -> refreshToken($refreshToken);

from apiClient.php

  /**
   * Fetches a fresh OAuth 2.0 access token with the given refresh token.
   * @param string $refreshToken
   * @return void
   */
  public function refreshToken($refreshToken) {

hi, I managed to access my own calendar using oauth v2 but I need to login everytime.

I would like to be able to access customer calendars to add/remove event like in this service :www.appointlet.com 

is your code below the right approach to reach this goal ?

thanks

the code above needs to be updated to 0.6 version of php google api library.

use this page https://code.google.com/p/google-api-php-client/ to help yourself to change the names of the included files and classes which are used in the code (changes are just often adding a Google_ prefix instead of Api or what).

Would you be able to help with my question here?

I believe my question is close enough to what you share here and I'm very near to achieving my goal as well.

Thank you in advance!
